Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • the invention is intended for simple road vehicles, in particular bicycles, light motorcycles, or vehicles powered by solar collectors or other relatively weak energy sources, to create a cheap, robust device for measuring the altitude covered, which is composed of simple components and which is quick and easy fold can be mounted on such a vehicle.
  • the usual speedometer which is already available anyway, can be used as the odometer.
  • the microprocessor processing the digital signals of the converter carries out the necessary mathematical combinations of the signals from the odometer and the angle encoder in a manner familiar to the person skilled in the art and stores the calculated values.
  • the stored altitude can be called up either directly or by pressing a button and displayed on a display device. If necessary, the signals are converted into an analog-to-digital converter before being fed into the microprocessor.
  • Positive angular deviations of the rotary encoder are defined as gradients and negative angular deviations as gradients.
  • a device is preferably provided which ensures that downward slopes are not taken into account or suppressed in the calculation of the vertical meters driven.
  • a zero position or various displays can be effected on the display device.
  • the meters in altitude can also be stored in a memory that cannot be deleted by pressing a button, which can only be deleted by a so-called “hardware reset” or the like. This value can also be brought up by key operation on the display keyboard.
  • the pendulum is equipped with a relatively large pendulum weight and a relatively short pendulum rod, which is sufficient in view of the relatively small accelerations of the vehicles suitable for the device according to the invention for a reasonably stable display of the vehicle inclination without further damping devices.
  • the device can be installed in an electronic tachometer of the vehicle, so that some components of the tachometer can also be used for the device according to the invention and thus a very simple, cheap and space-saving embodiment is achieved.
  • the zero position of the inclinometer can be adjusted either mechanically, for example by setting a fixed stop for the mechanically movable part of the inclinometer, such as the pendulum, or electronically.
  • an angle of 45 ° usually corresponds to a gradient of 100%.
  • the angle encoder and pendulum are surrounded by a common housing and the respective angles of rotation are scanned by a sliding contact sliding on a sliding resistor, the Grinding resistance is firmly connected to the inside of the housing and the sliding contact with the pendulum or vice versa.
  • This arrangement is extremely robust and easy to manufacture and provides relatively reliable values for the angle of nip.
  • the inclinometer has a rotation angle encoder 10, which is provided with a rotary potentiometer 12, on the axis 14 of which a pendulum weight 18 carrying a pendulum rod 16 of a mechanical pendulum is pivotally suspended parallel to the plane of the drawing.
  • the inclinometer 10 can preferably be suitably fastened to the frame, but if desired also to the fork or to the handlebar or stem of a bicycle or a corresponding part of another road vehicle.
  • Electrical connecting cables 22 leading out of the rotary potentiometer 12 can be connected in a suitable manner to the other electrical parts of the device.
  • the angle encoder 10 is connected to an analog-digital converter 24, which is the angle of rotation Converters detected analog measured value, such as an electrical resistance, to which the rotary encoder adjusts itself by the vertical position of the pendulum 16, 18 forced by gravity, converted into a digital signal.
  • This signal is sent to the subsequent microprocessor 26, which converts the signal into an angular deviation of the vehicle from the horizontal.
  • the signals of the electronic odometer 25 are also given to the microprocessor.
  • the angular deviation calculated by the microprocessor and the calculated distance on the basis of the signals from the distance meter 25 serve as the basis for the calculation of the vertical meters traveled or the current gradient of the roadway.
  • These values are either continuously given to a display device 28, or they can be called up by pressing a corresponding key on the keyboard 30 connected to the microprocessor 26 and then displayed on the display device 28.
  • the keyboard can also be used to cause the further provisions, deletions, displays and the like described above on the microprocessor 26 or display device 28.
  • FIG. 3 Another embodiment of the inclinometer with an electromechanical angle encoder 10 'is shown in Fig. 3.
  • the pendulum rod 16 is fixedly suspended on the axis 14 by means of a block 34 comprising the axis.
  • a grinding resistor connected in a suitable manner, not shown, to the other electrical parts of the device 38 embedded, which has the shape of a portion of a thin cylindrical ring.
  • a sliding contact 40 which is firmly connected to the block 34 and which is also electrically connected in a manner not shown, grinds on this cylindrical ring.
  • FIG. 5 shows a further embodiment of the inclinometer with a rotation angle sensor 10 ⁇ and a pendulum 16, 18.
  • Housing 32, block 34 and axis 14 are formed and stored in a similar manner as in the embodiment according to Fig. 3.
  • the grinding resistor 38 ' is, however, in this embodiment embedded in a side wall of the housing 32 on the inside and has the shape of an axis 14 surrounding annular disc.
  • the grinding resistance 38 ' is sensed by a sliding contact 40' projecting laterally from the block 34 '. Otherwise, the electrical circuit in this exemplary embodiment is the same as in the example according to FIG. 3.
